SDI Limited announced that sales in Australian dollars for the twelve months ending 30 June 2021 are estimated to increase by 18% to $79.6 million, compared to the corresponding period last year of $67.4 million. Sales growth has been driven by the continued increase in Aesthetic and Whitening products, partially offset by the decline in Amalgam products. The company estimates that after-tax profit, for the twelve months ending 30 June 2021, will be in the range of $7.5 million to $8.5 million, an increase of 77% to 101%, compared to financial year 2020.
